Abstract
An actuator is provided with a conductive polymer film portion, an electrode, and an electrolyte portion, and by detecting a waveform of a current that flows upon application of a voltage between the conductive polymer film portion and the electrode, a displacement amount of the actuator is detected so that based on the displacement amount thus detected, a voltage is applied to the conductive polymer film portion so that the displacement amount of the actuator is adjusted.
